The closed end of the member I3 is protaken substantially on lines 3-3 and 4-4 of Fig. vided with a centrally disposed opening 2| con- 2 looking in the direction of the arrows. centric with, but considerably less in diameter An oiler, such as is illustrated and described than the internal diameter of the member l3. herein, is susceptible of a wide variety of uses, The member l3 thus is provided with a bore 55 therethrough having a portion of relatively large diameter and a portion of relatively small diameter.

The tip 20 is provided with a longitudinally extending bore 22 that terminates at its inner end in a counterbore 23 in which is mounted a gasket 24 of suitable material such as rubber and constituting a valve seat, it being noted that the gasket 24 is in engagement with the righ-hand end of the member I3 and overlies a portion of the opening 2| in the closed end of the member l3, as clearly indicated in Fig. 2.

As previously stated, the oiler is valve-controlled, and the valve is clearly illustrated in Fig. 2, and comprises a portion 25 of a diameter such as to have a sliding fit within the member i3 and a reduced portion 26 that extends through the opening 2| in the closed end of the member l3 and has a sliding fit therein and is provided with a flat end adapted to engage the overhanging portion of the gasket 24 and seat thereagainst to form a valve seal.

The valve, although slidable in the member I3, is accurately and positively guided in its sliding movements to and from seating position, it being noted that the large portion 25 of the valve contacts the interior of the member i3 over a large area and thus the stability of the valve during its operative movements is insured and there can be no chance of the valve wobbling or getting out of position, particularly with respect to the alignment of the smaller portion 26 with the opening 2|.

Likewise, it will be noted that the contact between the portion 26 of the valve and the wall of the opening 2| in the member i3 is over a substantial area, thus providing an additional guide for the valve during its operative movements. In addition to engagement between the end of the valve and he gasket 24 is in the form of a large surface contact, thus eliminating likelihood of oil leakage and providing an effective seal.

The length of the reduced portion 26 of the valve is such that when the end of said portion is seated on the gasket 24 the large portion 23 of the valve is spaced inwardly from the closed end of the member I3, with the result that an annular chamber 2'! is provided between the portion 26 and the inner wall of the member l3 and such chamber may be designated as an oil supply chamber.

The chamber 21 is in communication with the hollow interior 28 of the valve by means of one or more openings 29 formed in the reduced portion 26 of the valve. A valve spring 30 is mounted in the member l3 and has one end abutting the enlarged end of the valve and its opposite end abutting a bushing 3| mounted within the inner reduced end l4 of the member l3. It will be apparent that the spring 30 normally maintains the end of the portion 26 of the valve tightly in engagement with the gasket 24 so that no oil can pass into the counterbore 23 and thence into the bore 22 of the tip 20. A relatively small diameter tube 32 has its reduced end 33 secured in the bore 22 of the tip 20 and there is slidably and loosely mounted in the tube 23 a valve actuating pin 34 of greater length than the tube so that its opposite ends can project beyond each end of the tube. The inner end of the pin 34 is provided with fins 35 to retain the pin in position in the tube, with the opposite end of the pin projecting beyond the outer end of the tube or tip a predetermined distance which results in limiting the amount of inward movement that can be imparted to the pin when the tip is applied to a point to be oiled and, in turn. limiting the opening movement of the valve and controlling the quantity of oil discharged therefrom. The diameter of the pin 34 and the internal diameter of the tube 23 are so related that there is a predetermined free area through the tube between the pin and the tube and this area acts to control the quantity of oil discharged through the tube.

The oiler is provided with a closure cap 33 which fits over the member l3, tip 20, tube 32 and pin 34 of the oiler and is threadedly connected by means of interior threads with the externally threaded portion ll of the reservoir II. The cap 36 is provided with a suitable spring clip 31 whereby the oiler can be fastened in a pocket or to some other part of the clothing of the user and carried ina manner similar to that in which fountain pens and pencils are carried.

The reservoir I0 is filled with oil by unscrewing the member l3 and its associated parts from the reservoir and pouring the oil in the open end of the reservoir while the latter is in a vertical position. The member l3 and its associated parts are then screwed into assembled relation with the reservoir in and the oiler is ready for use.

When it is desired to apply oil to a spot or part to be oiled the user removes the cap 36 and preferably presses the same upon the closed end of the reservoir. He then puts the outer end of the pin 34 at the point at which he wishes to deposit a drop of oil and pushes down on the oiler to cause said pin 34 to move inwardly until it contacts with the end of the valve and moves the latter against the action of the spring 33 to cause the reduced portion 26 of the valve to slightly clear the opening 2| in the closed end of the member I3. The operator then releases the downward pressure on the oiler, whereupon the spring 30 returns the valve to seated position on the gasket 24 and moves the pin 34 relatively outwardly or downwardly, as the case may be, with respect to the tube 32. The return movement of the valve to seated position forces a small amount of oil from the oil supply chamber 21 ahead of the end of the reduced portion 23 of the valve through the opening 2| and into the counterbore 23 and tube 32, from which it passes through the tube and down the pin 34 to the spot or place to be oiled. In this way a measured and non-excessive amount of oil is positively forced out of the oiler upon each operation thereof and is deposited from the end of the pin 34 in the form of a drop of oil upon the spot or place to be oiled.

It will be observed that the tube 32 is of such length and of sufficiently small diameter to enable oil to be applied at inaccessible points.

It will also be noted that the stability of the valve, due to the large guiding areas of contact between it and the member |3, assures a proper seating of the valve at all times, although the pin 34- is loosely mounted in the tube 32 and is free to have a limited amount of wobbling movement in said tube.

The effective valve employed in the oiler is seated at all times when the oiler is not in use and, therefore, there is no likelihood of the oiler leaking at such times, not even if it is arranged in a downwardly inclined or vertical position. The fact that the valve is stable and that a relatively strong spring 30 firmly holds the valve in seated position, eliminates any danger of the valve being jarred from unseated position during 75 non-use, and causing a leakage of the oil. The oil supply chamber 21 being always in communication with the reservoir chamber through the opening 29, the counterbore 28 and the interior of the member i constantly has its supply of oil replenished from the reservoir chamber.

Although a preferred embodiment of the invention has been illustrated and described herein, it will be understood that the invention is susceptible of various modifications and adaptations within the scope of the appended claims.
